Abstract
The design and implementation of distributed High Performance Computing (HPC) applications is becoming harder as the scale and number of distributed resources and application is growing. Programming abstractions, libraries and frameworks are needed to better overcome that complexity. Moreover, when Quality of Service (QoS) requirements such as load balancing, efficient resource usage and fault tolerance have to be met, the resulting code is harder to develop, maintain, and reuse, as the code for providing the QoS requirements gets normally mixed with the functionality code. Component Technology, on the other hand, allows a better modularity and reusability of applications and even a better support for the development of distributed applications, as those applications can be partitioned in terms of components installed and running (deployed) in the different hosts participating in the system. Components also have requirements in forms of the aforementioned non-functional aspects. In our approach, the code for ensuring these aspects can be automatically generated based on the requirements stated by components and applications, thus leveraging the component implementer of having to deal with these non-functional aspects. In this paper we present the characteristics and the convenience of the generated code for dealing with load balancing, distribution, and fault-tolerance aspects in the context of CORBA-LC. CORBA-LC is a lightweight distributed reflective component model based on CORBA that imposes a peer network model in which the whole network acts as a repository for managing and assigning the whole set of resources: components, CPU cycles, memory, etc.
